Rollover elite credit does encourage continuing to book revenue fares (rather than switching airlines or shifting to award flights). It seems likely that DL will be learning this in about a year.

It should also be noted that the ULTI rollover limit is arguably a true improvement from the previous ULTI program as far as rollover is concerned (as there was no UXP rollover before), so the introduction of UXP rollover isn't evidence of a desire to squash rollover by AFKL. This may be a manifestation of confusion between UXP and XP, though.

If there is a fear that there are too many Platinums sitting on XP balances and waiting out their PfL status without flying revenue fares, there are more effective ways of dealing with that which preserve rollover. For example, a Diamond or Titanium level could be introduced at 500 XP with marginally improved benefits over Platinum which would soak up rollover XP. Alternatively an annual AFKL revenue segment or credit card requirement could be instituted for Platinum rollover.
